IMPROVEMENT IN WINDMILLS.

To all whom 'it may concern Be it known that I, G. S. JENKINS, of Landsdale, in the county of Montgomery, and State of Pennsylvania, have invented a new and useful Improvement in Windmills; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which- Figure l is a vertical section of my improved windmill.

Figure 2 is a front view of the wheel, when adjusted to receive the full force of t-he wind.

Figure 3 is a detail side view of the hub and wheels, to which the fans or arms of the wheel are attached.

My invention has for its object to improve the construction of windmills, vso as to make them more convenient in use, more effective in operation, and more under the control ot' the operator, than when construcgted in the ordinary manner;- and n It consists in the construction and combination of .various parts o f the machine, as hereinafter more fully described.

A is a horizontal shaft, which revolves in bearings attached to the bed-plate B.

To the outer end of the shaft A is rigidly attached the hub c1 c2I of the wheel (l, the rim ca of which is securely attached to the spokes c,l four, more or less, of which should be used.

I) is a wheel, similar in construction to the Wheel Gexcept thatfit may be made lighter, and the hub d of which works loosely upon the shaft A, so that it may slide longitudinally, anda't the same time revolve or partially revolve upon said shaft A.

E are the four ,arms or wings, to which are attached bars or irons, e, 'the ends of which are bent upward, or have upwardly-proj ecting pivots brmed upon or attached to them, which pass through holes in the lims c3 dz of lthe wheels O and D, in such a way that the wings E may be set parallel with or inclined to the shaft A, by simply moving the wheel D toward or from the wheelO, which said movement of the wheel D causes it to revolve slightly uponthe shaft A.

,lo the lower ,ends of the wings E are attached, or

upon them are formed pivots e2, which enter the hub cl c2 of the wheel C, and support the wings in such a way that the pivots el cannot drop out of the wheels C D, while at the same time the said wings may bev turned freely, to adjust them in the desired position.

The hub oi' the wheel C is made in two parts, c1 c, the part c being permanently attached to the shaft, and being recessed upon its inner end, to receive the end of the other part, c2, which moves upon the shaft A, and is'secured in place, when moved close up to the y The Schedule'referred to in these Lettere Patent and making part of the same.

part c1, by a pin or bolt,fpassiug through the said part cz and through the'shaft A, as shown in gs. l and 3.

The part c2 is also grooved longitudinally upon one side, as shown in g. 3, so'that by removing the said key, and the pin or bolt by which 4the part c2 1s secured to the v shaft A, the said part c2 of the hub C may be turned, so that the pivot of any desired wing may drop down into said groove, allowing the said wing to be conveniently removed for repairs or other desired purpose.

To the shaft A is attached a crown-wheel, F, the

.teeth of which mesh into the teeth of the long gear or pinion-wheel G, attached to the upper end of the vertical driving-.shaft H, the lower end ofwhich rests and revolves in a step, I, placed iu the socket J, attached to the base ofthe supporting frame-work K.

The vstep I is hung from the ends of the forked lever L, which is pivoted to some suitable support, and the free end of which extends out along a ratchet-bar, M,

attached to a post of the frame K, .or to some vother suitable support, so that, by means of the lever L, the shaft H may be raised and lowered, and held in any desired position.

N is a two-armed lever or shaft, which is pivoted to some suitable support, attached to or connected with the bed-plate B.

The end of one arm of the lever or shaft N rests upon the upper end of the shaft H or gear-wheel G. The end of the other arm of the lever or shaft N is connected with thelever O by the connecting-rod I).

One end of the lever O is pivoted to the bed-plate B, and its other end is forked, and rides upon the grooved end of the hub of the wheel D, so that the said wheel'may be mo'ved to set the wings E, by simply raising or loweringthe shaft H.

To the side of the bed-plate B, opposite to the rings E, is attached an arm, Q, having a vane, It, attached to its outer end, so as to always hold the fans or wings E toward the wind.

To the under side of the bed-plate B is securely attached a plate, S, having a tube or socket,"l, securely attached to it, through which the shaft H passes, and which projects downward through the platform la of the'frame-work K, upon which the bed B rests.

To the lower end of the socket T is attached a wing, U, to connect the bed-plate B and its attachments securely to the platform It.

The bed plate B Arests upon friction-wheels V, pivoted to supports attached to the platform le', to diminish friction, and enable the bed-plate B to be more readily turned by the vane It. n

To the forward end of the hub c or of the shaft A are attached one or more springs, W, the ends of which are connected with the wheel D by the connectingrods X, so as to hold thc vsaid wheel l) forward, and

give steadiness toit, in whatever position it may he adjusted.

Having thus described my invention,

What I claim es new, and desire to secure by Letters Patent, is-

1. The wind-wl1eel, formed by the combination of the Wheels C D and Wings E, with each other and with the shaft A, substantially as herein shown and described, 2md- `0r the purpose set forth.

2. The hub cl e2 of the wheel C, formed in two parts, substantially as herein shown end described, and for the purpose set forth.

3. Detachably-pivoted wings E, to the hub c1 czzmd lVitnesses:
